Y VISIBLE DISPENSING DEVICE Filed May 29, 1929 UNITE,

ROBERT W. COBB, OFA JAMESTOWN, NEW

STATES NEW YORK YORK, ASSIGNOR TO JULIAN PUMP AND l MANUFACTURINGCOMPANY, OF JAMESTOWN, NEW YORK, A CORPORATION OF VISIBLE DISPENSING:DEVICE Application mea May y2e,

This invention relates to an improvement in a visiblefdisp'ensing devicefor gasoline pumps and the like. l

In its preferred embodiment this invention ,5 contemplates the provisionof a device adapted to be mounted upon a gasoline pump of the Wetordry'hoseftype whereby the actual dispensing of gasoline isy visiblybrought to the attention ofthe purchaser thereof.

Prior to thisfin-vention devices of this generalV type havebeen in usebut, due to regulations in certain States relating to the visibledispensing of gasoline, these devices fail to fulfill the purposeintended. Since the States arenot'wholly in accord in their requirementsit is essential that avisible dispensing device embodying all therequired features be provided. Applicant has therefore produced a devicewhich, while indicating the iiow of gasoline therethrough,y alsoprevents the ac- @umu-lation of air in the dispensing line and which isequally applicable for use in conjunction with pumps of the wet or dryhose type.

Theprinci-pal' object of this invention is to provide a-device of thisclass indicative of the amount of gasoline contained within thetransparent domey through which the gasolinel must passduring; the'dispensing operation.

Anotherobj'ect of this invention is to providev a device of this classwhich clearly indicates to the purchaserl that gasoline is actuallybeing'dispensed.

A further=objectjofthis invention is tolprovide a device of this classof'economical construction and adaptable for both wetk and dry hose typepumps and which complies with the laws of certain States relating to thevisibledispensing of gasoline.

@ther and further objects ofthis invention will appear from aconsideration of the following specification taken in conjunction withthe5 accompanyingy drawing, andi in which Fig. 1 is a front elevation ofa gasoline pump ofthe wet'hose type showing one modiicati-on of thisinvention mounted thereon;

let passages for the gasoline and the means by which oscillation of thegasoline within the dome is obtained; and

Fig. 3 is a plan view of the device with the glass dome removeddisclosing further struc* turalI details of this invention.l

Referring to the drawing and particularly to Figure 2 thereof, thisinvention comprises a base generally indicated by the reference numeral'10. The base 10 is provided with a gasoline inlet passage 12 and outletpassage 13.' Encircling the passages 12 and 13 and formed in the upperface 14 of the base is an annular depression orrecess 16. Centrally ofthe face 14 an angular boss 17 is provided. A threaded opening 18 isprovided in the slanted face of thevboss 17 and a deflector or baffleplate 2O is secured to this face by means of the screw 21. The plate 20,being mounted substantially at a Aforty-tive degree angle to the face 14ofthe base 10, closely approaches the substantially vertical wall of theglass dome 25. The purpose of this is to insure sufficient oscillationof the liquid as it passes through the dome to indicate to a purchaserthat the pump is working and gasoline is being dispensed.

Mounted within .the annular recess 16 is a suitable gasket 26. The glassdome 25, lterminating in a flanged rim 27 is adapted to restwithin thedepression 16 upon the gasket 26. A second gasket 29 is placed upon theupper face of the rim 27 of the glass dome and a clamping ring 31 restsupon the gasket 29. v

Extending downwardly from the upper face 14 of the base 10 andexteriorly ofthe recess 16 are a plurality of threaded openings 33. Theclamping ring 31 is provided with outwardly extending bosses 34 each ofwhich has formed therein a vertical opening 35, the number of openings35 corresponding to the number of drilled openings 33. The glass dome 25is drawn down into sealing engagement with the gasket 26 through the useof'bolts 37.

LocatedV within the glass. dome and prior to the mounting thereof luponthe base 10 is a ball 38 formed from cork or other suitable lOatngSubstance When this device is used in connection with gasoline pumps ofthe dry hose typre, the normal position of rest of the ball 38 issubstantially as shown in dotted lines, Figure 2 of the drawing,covering the inlet opening 12. However, when this device is in use upona pump of the wet hose type as illustrated in Figure 1, the balloccupies a position of rest adjacent the head of the glass dome as shownin full line of Figure 2. A wet hose type pump maintains gasoline at alltimes in the 'system directly down to the nozzle of the dispensing hose,whereas, a pump of the dry hose type is required to be operated to causegasoline to flow throughthe glass dome 25, passage 13 and hose 39.

The above described device, although applicable for use uponpumpsofeither the dry or wet hose type, is usedmore often upon the`latter type. This is due to the fact that nearly all types of dry hosepumps are provided with a visible gasoline container from whichdispensing takes place. However with apump such as shown in the drawing,there is no visible means of indicating that gasoline is-actually beingdispensed withoutfthe attachment of applicants device.

When the pump is of the gasoline.V Thus, when further dispensing iscarried on, the pump will fail to give absolutely accurate measure. Thelaws of certain States require that no such condition eX- f ist andconsequently applicant through the use of the float 38 and plate 20 isable to instantly cause the removal of an air pocket in the dispensingdome. As gasoline enters the passageway 12 it moves upwardly toward thetop of the dome and, ,following the contour thereof, is directed uponthe plate 20. A part of the gasoline passes out through the passageway13 andl theremainder sets up a swirl- .ing motion causingy the float 38to oscillate rapidly about the dome. With each oscillation of the floatit causes a small'amount of air to pass out through the passageway13until only gasoline remains within the dome. It is to be understoodthat'themotionof the float about the dome is very rapid and consequentlyany air pocketed in said dome is removed almost instantly. It is to befurther understood that, except under conditions as above described, thedome will be filled at all times with gasoline and the float will restagainst the top of the dome. 1

Attention is directed to the fact that a Y first operated or directly yafter having run dry, no gasoline is contained customer need only Awatchthe glass doine and the float within it to determine whether or notgasoline is being properly dispensed.

The purpose of this device when used in conjunction with pumps ofthe dryhose type is identical. However, when this type of pump is not operatingthe float rests upon the mouth of the passageway 12 where it can receiveand be oscillated by the first flow of gasoline into the dome. I n yWhile only one modification of this invention has been shown anddescribed, applicant does not intend to be limited thereto since it isobvious that other modifications and adaptations may be made withoutdeparting from the spirit and scope ofthis invention as vset forth inthe following claims. y f i Having thus set forth my invention what Iclaim is new and for which I desire pro-z.
